A display device includes a transparent laminated body 6 formed of transparent substrates 1 that are arranged in layers; an image display body 2 that faces the transparent laminated body 6; and a resin layer 3 that is disposed between the transparent laminated body 6 and the image display body 2 and is made of a photo-curable resin. The transparent substrates 1 are bonded with a thermal adhesive film 5. The thermal adhesive film 5 has optical transmittance of 50% or more at wavelength of 395 nm and optical transmittance of 10% or less at wavelength of 365 nm.

There is disclosed a road sign plate comprising a base plate (2), a series of LEDs (4) arranged on said base plate and supply means associated to said series of LEDs in which, particularly, there is a first resin layer (1) laid on which covers, at least, the base plate (2) and a second resin layer (7) arranged over said first resin layer, wherein said second resin layer (7) is of a translucent material. This road sign plate is not expensive, features great capacity of mechanical strength and electric resistance and improved translucency properties.

An apparatus includes a support member forming a plurality of seats, wherein each seat is adapted to secure an upper end of a yard stake. The support member is further adapted to support at least two retainer arms, and each retainer arm has a distal end including a hook adapted to secure an edge of a display object. The apparatus may be used to assembly a display easel, such as may be used to display a yard sign. The support member may be a rigid block or a wire bracket. A kit may include some or all of the components of a display easel. The support member may be elevated above the ground using yard stakes.

The application provides a floor tile screen, comprising a box body (1), a rear body (2), a PCB board (3) and a front body (4), wherein the rear body (2) is fixed on the box body (1); the PCB (3) is arranged between the rear body (2) and the front body (4), and provided with lamp beads; a plurality of transparent fixing columns (41) are fixedly arranged on the front body (4), pass through the PCB board (3), fixedly connected with the rear body (2), and avoid the lamp beads. The fixing column (41) has the function of limiting the front body (4), the front body (4) and the rear body (2) are connected together by fixing columns (41), to avoid separation; the fixing columns (41) are transparent, so that the light emitted by the lamp beads is not blocked, the display effect of the floor tile screen is improved.

Aspects of the disclosure are directed to a multi-functional streetlight. In accordance with one aspect, the multi-functional streetlight includes a hexagonal shaped support structure, wherein the hexagonal shaped support structure includes an arm segment and wherein the arm segment includes a luminaire on an under side of the arm segment; and a base flange configured to couple the hexagonal shaped support structure to the ground.

A signaling device for increasing visibility of a mobile robot. The signaling device comprises a signaling section, a body section, and a base section. The invention also discloses a system for increasing visibility of a mobile robot. The system comprises a mobile robot, a signaling device attached to the mobile robot and a remote terminal configured to at least one of monitoring and controlling at least one of the mobile robot and the signaling device.

A light-emitting sign device according to the present invention comprises: a solar cell; a battery module comprising at least one battery in which power generated by the solar cell is stored; a light-emitting module for emitting light by the power supplied from the battery; a front panel optically coupled to the light-emitting module; and a controller for applying, to the light-emitting module, a target mode determined, from among driving modes, on the basis of an average value of solar cell voltages measured for a certain period with respect to the solar cell and a voltage value of a battery voltage measured at a certain time with respect to the battery module.

A joint for a signpost having a first segment and a second segment is provided. The joint includes a first cap for the first segment, a second cap for the second segment, and a multi-directional hinge coupleable between the first cap and the second cap. The hinge is pivotable to facilitate lateral movement of the first cap relative to the second cap.

A road sign having two parts connected by a hinge that is arranged to obscure text in a retracted state but which exposes the text in a deployed state when the sign automatically deploys in response to a triggering event such as a power outage.
